This disk contains the data files used to generate the results in Table 1 
of Berry and Berry's article, "Tax Innovation in the States," American 
Journal of Political Science, August 1992 (and other models reported in the 
text of the article).

Throughout, variables ending in '_1' indicate variables lagged one year.

In all data sets, a field which is completely blank indicates a missing 
observation.

It is recommended that before undertaking different analyses than those used
by Berry and Berry, users reproduce the results in Table 1 using probit
to make certain that the data sets on this disk have not been changed from
the original versions.

FILE = "cols3&4"

The file "cols3&4" contains the data that yield the results in columns 3 and
4 of Table 1 (and other supplementary models reported in the text).
The analysis reported in column 4 relies on all 232 cases in 
the file; the analysis in column 3 excludes cases for which the variable 
'fiscal_1' is missing.
